摘要
采用样地调查法研究云南省华坪县海拔1 240~3 060 m蚂蚁群落多样性规律.共采集蚂蚁15 077头,隶属于5亚科21属46种,其中包括42个已知种和4个待定种.分析结果表明,黑头酸臭蚁、罗思尼斜结蚁、沃森大头蚁为华坪县的优势种,占物种总数的6.5% ;常见种有10 种,占21.7% ,稀有种有33种,占71.7% ;蚂蚁群落的物种数目为1 ~22 种(平均值9.3 种) ,个体密度0.4~1 299.8只/m2(平均值376.9) ,多样性指数0 ~1.617 2 (平均值0.634 4) ,均匀度指数0 ~0.539 8(平均值0.249 1) ,优势度指数0.278 1~1.000 0(平均值为0.700 7) ;不同海拔和植被类型蚂蚁群落之间相似性系数0~0.448 3(平均值0.064 2) ,处于极不相似至中等不相似水平,说明华坪县蚂蚁群落具有各自的特点.
Abstract
The ant diversity between the altitudes 1240－3060 m in Huaping County of Yunnan Province was studied by sample－plot method. This research collected 15077 ant individuals which were recognized as 46 species belonging to 21 genera and 5 subfamilies, including 42 known species and 4 unknown ones. The results showed that the dominant species were Tapinoma melanocephalum, Plagiolepis rothneyi and Pheidole watsoni, accounting for 6.5%. The proportions of 10 common species and 33 rare ones were 21.7% and 71.7% respectively. The main diversity indexes were as follow, species numbers 1－22 ( average 9.3 ) , individual densities 0.4－1299.8 ( average 376.9 ) , species diversity indexes 0－1.6172 ( average 0.6344) , evenness indexes 0－0.5398 ( average 0.2491) , dominant indexes 0.2781－1.0000 ( average 0.7007) . The similarity coefficients of ant communities with different altitudes and vegetation forms were 0－0.4483 ( average 0.0642 ) at extremely dissimilar to moderate similar levels, which represented that each ant community had its own characteristics.
